nowadays, liveliness and rapid maintenance of the development process of the companies are dependent on the accurate and complete understanding of the merits of the financial activities. since these merits are relative concepts that are based on comparisons, lists of ranking and comparison of industries with each other act as useful signposts for managers, politicians, and investors. the point ...

Multicommodity distribution problem is one of the most interesting and useful models in mathematical programming due to its major role in distribution networks. The purpose of this paper is to describe and solve a special class of multicommodity distribution problems in which shipment of a commodity from a plant to a customer would go through different distribution centers. The problem is t...

A Multi-objective optimization procedure has been developed to determine some kinetic parameters of free radical polymerization of vinyl acetate based on genetic algorithm. For this purpose, mathematical modeling of free radical polymerization of vinyl acetate is carried out first and then selected kinetic parameters are optimized by minimizing objective functions defined from comparing exp...

The classification of fuzzy data is considered as the most challenging areas of data analysis and the complexity of the procedures has been obstacle to the development of new methods for fuzzy data analysis. However, there are significant advances in modeling systems in which fuzzy data are available in the field of mathematical programming. In order to exploit the results of the researches on ...

Proof planning is a novel knowledge-based approach for proof construction, which supports the incorporation of mathematical knowledge and the common mathematical proof techniques of a particular mathematical eld. The diagonalization proof technique is a well-known method in theoretical computer science and in mathematics that originated with Can-tor, who used it to show his seminal uncountabili...

This paper presents a systematic approach to develop the mathematical model for predicting the ultimate tensile strength, yield strength, and percentage of elongation of AA6351 aluminum alloy which is widely used in automotive, aircraft and defense Industries by incorporating (FSW) friction stir welding process parameter such as tool rotational speed, welding speed, and axial force. FSW has bee...

The aim of this study was to develop an optimal sustainable forest plantation based on goal programming and Analytic Hierarchy Process (AHP) methods. This study was carried out in Guilan province, north of Iran. First of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological Makhdoum Model by ...

A considerable problem in competitive trade world is choosing the best supply chain. As a result in much more serious circumstances of competitions looking for the best supplier for manufacturing, for preparing raw material, is very significant. Meantime suppliers have different scenarios to be fulfilled, such as changing selection variables like lead-time, transportation cost and transportatio...
